I'm selling my truck. I already have 2" drop shackles. Guy wants it 4" total drop. I looked into hangers and leafs. There doesnt seem to be as much info out there for 4" drops as there are 6/7 drops. WHat is the better route and where is the best place to get this stuff? I never really looked into it much. Iv'e lowered several trucks but not a gmt900. I assume its the same principle but you never know what issues arise in different applications. Basically I don't want to mess with pinion angle, deal with a crap load of prep work etc etc. or install a known crappy product but save money on a good distributor.

 

Belltech 3" drop shackles and pull the factory 1" lift blocks out. After all the screwing around with stuff on my truck this is what I finally used and stayed at. Gives you about 4" total drop Used this in the rear and belltech drop struts up front set at 2"

At first I was 4/7 then 3/5 now at 2/4

 

There is no true way of getting a 4" drop with just shackles. That is still a 2" shackle with you pulling the lift block for 3" total.

Flip kit gives you 7". Add the shackle flip kit with stock shackle gives you 6". Add the 2" drop shackle as a lift shackle that is 5" at the first hole closest to bushing, 4" at the last hole. You can always pull a leaf spring which i wouldnt do or put drop leaf springs on which i wouldnt do.

My truck is 4/6 on oem 20s 275/55/20

 

I did shackles pulled the block and pulled the overload. Truck sits nice and rides smooth and best of all it was cheap.

 

Wow. I'd really be interested to hear what setup you had for each level and why you went the direction you did.

 

I have Mcg drop leaf springs and belltech drop shackles with belltech street performance shocks and gave a total drop of 5 inches..the ride is super smooth
